【 Weak current College 】 CCTV new North with floor fire causes of

February 9, 2009, CCTV in the discharge of the Lantern Festival Fireworks tall fire occurred, resulting in a number of casualties and significant property damage. On the field of fire cause Fireworks, is controversial. Invisible from the surface, the CCTV new site fire is due to the discharge of fireworks (mainly refers to the shell), but in my view, not fireworks will cause a fire. If you organize the implementation of management and technology plan design, strict implementation of the relevant national administrative rules, safety regulations for firework display requirements, there are administrative approval procedures, setting off the Fireworks product quality, job, construction, design, operations officer for the discharge and discharge the security warning, and so do the work, and mutual coordination and harmonization, the fireworks display, setting off fireworks is able to achieve a safe, successful, this field because of the Fireworks CCTV for discharging the tragedy caused by the fire is completely avoidable.
I tried from fireworks display of job programme perspective, on the field because of the fireworks display caused by fire several possible causes for point superficial analysis and coherence to ensure that the views of the fireworks display security.
The Ministry of public security under People's Republic of China on 8 September 2005, on 1 January 2006, the fireworks of fireworks and pyrotechnic safety regulations (GA183-2005): discharge of job programme by the technical design and implementation of programmes. Technical design of the programme is responsible for discharging operations unit responsible for the formulation, implementation of programmes by the organiser is responsible for organising and formulating.
Analysis of analysis are discussed, caused the CCTV Lantern Festival Fireworks fire deep-seated reasons, first is to assume that the CCTV's operations of firework display, in the development of its discharge of technical design of the programme has a number of deficiencies, followed by fireworks display of sponsor (CCTV departments) in drawing up the Organization and implementation of programmes is also wrong. In view of these two factors, finally led to the occurrence of fire.
First, the operation unit in technical design reasons:
Learn from various channels of some relevant information to analysis, the author believes that in the field of the fireworks display of job schemes exist the following shortcomings:
1. improper discharge site selection. It is understood that the CCTV Lantern Festival fireworks display space is in Beijing-Guangzhou Railway Bridge near the CCTV's new building near the North with floor space. This site is not suitable for discharge of setting off shell, because shell around buildings especially in high-rise buildings in blast, fire insurance, a greater impact. In General, shell height of planes, large coverage area after the explosion, such as 3 shell height of planes at 90-100 metres, covers a radius of 25-30 meters, covering an area of 2000-2800 and 6 shell of planes, height 150-160 m, coverage of 55-65 meters, covering an area of 9500-13000 square meters. CCTV new site North allegedly with floor space of around 200 meters long, 30 meters wide, surrounded by the large tall buildings, the entire space of about 6000 square meters, as a predetermined area is too small, the discharge of shell is easily shell exploded when the ignition ignition of flammable materials in the vicinity, causing a fire.
2, product variety selection. It is understood that the total use of fireworks 700 multiple shell, Shell's specifications is 3 inches to 6 inches, the number and variety of potted flower flower is unknown. Potted plant launches height generally 40-50 meters, expand the range of 25-50 m, which shows that shell fire probability to much more than a potted plant. In technical programmes, should select the potted plant, bouquet, Roman candles, fountains, etc., explosive small or non-explosive Fireworks varieties, instead select the shell, this is the technique of design-time selection of varieties. In fact, at the Olympic Games opening and closing ceremonies, the bird's nest, and other buildings and environs, fireworks display of varieties are potted flowers, bouquets, Roman candles, fountains, etc., but does not include shell, thereby ensuring that the Olympic Games opening and closing ceremonies of the discharge of security. Unfortunately technical design without drawing on the successful experience of the Olympic Games, on the contrary, it is desperate to use a shell thrown the CCTV building fire.
3. safety distance not enough factors. According to the Fireworks fireworks display Security Statute, Fireworks, A level with the minimum safe distance is 280 m, b level is 200 m, and C-level is 100 m, where the minimum safe distance refers to the discharge point margin and the minimum level of the audience, this is to consider the safety of the audience. Considering the discharge of shell on buildings, discharge point and high-rise buildings of distance also should increase. But this new CCTV building North with floor fireworks display, avoid shell on high-rise buildings of the safety distance is not enough, up to 100 meters. While the shell's coverage area and a large, easy to ignite nearby objects, resulting in a fire. It is worth noting that the North with nearly 100 m above the floor, some shell height and of the explosion of equal or slightly higher, shell is next to the North with floor or floor to the top of the explosion, it may cause fire, North with floor. Where is allegedly was dynamited shell landed on the roof, because the roof is flammable of waterproof material, there was a fire first.
4, meteorological factors affecting drying. According to meteorological data, Beijing has 106 days has no effective precipitation, air drying, some inflammable materials easier to catch fire. Although the 9 February night, CCTV new site building in the region of the surface wind 0.9 m/s, belongs to the breeze, the wind is formed basically does not help the situation of serious fire. But air drying is the result of external factors on fire-prone.
5, high buildings. CCTV's new building North with floor lines up to 30 layers of high-rise buildings. This ultra high buildings caused a fire quickly, spread wide, fighting hard. There is a major reason is the personnel action not conveniently, the second is the fire truck spraying water height is limited, only 30-40 metres high, it is difficult to fight over the height of the burning parts of the source of fire. The third is the high-rise building on the formation of the elevator shaft, etc., with exhaust chimney effect, so that the spread of fire and smoke flow very fast. Even in external wind small, tall buildings will alsoThis in the fire spreading speed than low-level building fast, and the fire is burning and more. Fourth, because the building high-rise buildings, function room, indoor decoration, and thus has a lot of fuel, i.e. fire load, fire load greater demonstrate a fire burning, burning of long duration. So tall building by the fire.
Second, the organizers in developing, organizing and implementing programmes.
Fireworks safety regulations for the fireworks display, sponsor organizations implement Fireworks, should establish command, Commander, headquarters is set by the organisers in charge, unified command leading display technology, security, surveillance, traffic control, fire, ambulance and emergency and other functions of the Group's work. Analysis under the circumstances, the organizers did not seriously consider fireworks display when the safety guard and fire, ambulance and emergency treatment. Such as:
1, the security warning. As organizations in the implementation of the security guard is not enough, the fire occurred when entering and leaving the building part. In accordance with the safety distance of discharge and the security guard, the fireworks display to discharge within 30 minutes after the end of, and are not allowed in addition to the discharge of engineering and technical personnel other than the in and out of the discharge area, and from that time discharge area, North with floor should be at the discharge area or discharge of the edge of the region. Here the organizer should advance the clearance and to halt and leaving the building, not related to staff in order to avoid casualties. This is noteworthy.
2. fire. According to the analysis, in the discharge fireworks, no arrangements appropriate fire trucks and fire officers in the discharge area next to the on-call to the rapid fire and any time on the fight against fire. Until the fire alarm so that only delayed the valuable time of extinguishing fire.
3, security assessment. According to the existing situation analysis, if the sponsor fails to Beijing Municipal Public Security Department to handle fireworks display and approval procedures, the sponsor may not conduct fireworks display of safety assessment. While the security assessment is a sponsor organization on departments organise fireworks safety, science, and other elements are evaluated to determine whether or not Fireworks held an important scientific basis. No security assessment, no scientific proof to guarantee the safety of the Fireworks, and ensure the safety of persons and property. This is also the sponsor of the deficiencies.
To sum up, CCTV Lantern Festival Fireworks because of the risk of job programmes and organizations on a number of problems that led to the final event of fire. Therefore, we must follow the scientific laws, resolutely implement the fireworks of fireworks and pyrotechnic safety regulations, scientific design fireworks display job programmes and organize the implementation of the programme, ensuring that each fireworks display of security and foolproof.
